1. Conjugation of verbs in Conditional Tense

Regular Verbs

The conjugation of verbs that are regular in Conditional tense is easy, because of 2 reasons:

It doesn’t matter if the verb’s infinitive ends in “-AR”, “-ER” or “-IR”. The endings are the same for all types!

We attach the endings directly at the end of the Infinitive.

The endings are the ones presented in this table:

Person

Ending

yo

-ía

tú

-ías

él

-ía

nosotros

-íamos

vosotros

-íais

ellos

-ían

For example, here are the full conjugations of the verbs “amar”, “ser” and “sentir” in Conditional Tense:

amar

ser

sentir

yo

amaría

sería

sentiría

tú

amarías

serías

sentirías

él

amaría

sería

sentiría

nosotros

amaríamos

seríamos

sentiríamos

vosotros

amaríais

seríais

sentiríais

ellos

amarían

serían

sentirían
